55e4803b61 PCI: tegra194: Ring doorbell If DMA is not running 
Issue:
During multi threaded testing, there are cases where EDMA HW enters
stopped state even through there are pending descriptors to process.
This happens even when doorbell is rung after updating descriptors and
barriers places.

Fix:
After processing channel interrupt, ring doorbell, if there are pending
descriptors and for that channel is not running.

1733a8ddee pci: tegra: Fix build for Linux v6.1 
Upstream Linux kernel commit f2042ed21da7 ("iommu/dma: Make header
private") made the header "linux/dma-iommu.h" a private header file and
so compiling the Tegra PCI EDMA driver for Linux v6.1-rc1 now fails
because this header is not found. On further review, instead of
including "linux/dma-iommu.h" it is only necessary to include
"linux/dma-mapping.h" instead.
